' GEARY E. CARSON, OF ALBANY, NEW YORK.

WINDOW-FASTENER.

T 0 all whom t may concern:

Be 1t known that I, GEARY E. CARSON, a

' citizen of the United States, and a resident of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Window- Fasteners, of which the following is a specification.

My invention relates to improvements in window fasteners, and, in the embodiment' illustrated and described, is particularly adapted for the windows of railway cars, although it will be obvious to those skilled in the art, that it is useful in many situations and other connections.

In railway cars it is common to provide a rack carried by the window frame and a latch carried by the window sash adapted to coperate with one another so that the window may be fastened at various heights. It is customary to overhaul and refinish railway cars frequently and, in so doing, all fixtures are removed for the purpose of renishing, the metal fixtures being sent to a metal refinishing department for cleaning and polishing, while the other fixtures, such as window saslies, are sent to another refinishing department for cleaning, revarnishing or repainting and the like. It is common to secure the racks and latches above mentioned, in place by means of screws and consequently to remove them the screws must be removed, and after a number of such removals the screw threads become worn and it is necessary to rebore and rethread the screw openings and to use large screws. Especially is this true in the modern steel car, where the sheet metal to which these parts are attached is very thin and the screw threads therein easily become so worn as to be incapable of holding the parts in place. Furthermore, the removal of the numerous screws for the purpose above mentioned requires considerable time and labor which is an important item of expense n the refinishing of such cars.

The main object of the present invention 1s to Vprovide an arrangement by means of which such screws or bolts are avoided for securing these fixtures in place whereby the time and labor necessary to reboring and rcthreading, where the screw threads have become worn out, is eliminated, and also by means of which these fixtures are very much more quickly removed for refinishing there- Specification of Letters Patent.

by saving a large amount of time and labor in the operation of overhauling for refinishing. A further object of the invention is to provide arrangements by which such fixtures are also easily and quickly secured in place either at the beginning or after refin ishing. It is estimated that in an ordinary 70 foot car having forty-two double windows and two single windows, the labor cost of applying fixtures made in accordance with my invention will be only 20c as compared with over $4. for fixtures now commonly in use. And to remove the fixtures it is estimated that the fixtures in my invention may be removed at a labor cost of 20c as compared with a cost of over $1 for similar fix tures now generally in use.

Further and more specific objects, features and advantages ,will more clearly appear from the detail description given below taken in connection with the accompanying drawings which form a part of this specification.

In the drawings :-Figure l is a side view of a window having coperating therewith an arrangement embodying my improvements in their preferred form, certain parts being broken away and shown in section in order to more clearly illustrate the improvements. Fig. 2 is a section taken substantially on a line 2 2 of Fig. l. Fig. 3 is a section taken substantially on a line 3-3 of Fig. l. Fig. l is a section taken substantially on the line of Fig. l. Fig. 5 is an enlarged detail view of one of the latches partly broken away to more clearly illustrate the same. Fig. 6 is an edge view of the latch shown in Fig. 5. Fig. 7 is a view similar to Fig. 5 but showing a modified form of latch.

Referring to the drawings, l represents a glass window fitted in the window sash 2 within a window frame provided with a window seat 3 and side frame members 1l, f-l. Secured to or forming part of the side members of the window frame are sheet metal members 5, 5, one on each side of the window frame, and each provided with an outer flange 6 forming an outer guide for the sash 7 of an outer window 8. One of the members 5 is clearly shown in Fig. 2, and each is provided with a series of three slots 9, 9, 9 each having a reduced lower end portion l0. Each plate 5 is also provided with a set of three slots 11, 1l, l1, each having a reduced lower end portion 12. v 13, 13 represent rack members provided with a vertical row of rack teeth 14 and a curtain guide groove 15. Formed integral with the back side of these rack members are cleats or keys 16 adapted to be slipped through the slots 9, and then when the racks 13 are dropped downwardly, the cleats engage behind the narrow portions of the slots at 10 and form a wedging fit therewith so as to securely join by a slip joint the rack members 13 to the member 5, but so that they are easily removed therefrom.

Screwed on to the window sash 2 are plates 17 provided with slots 18 having` laterally extending reduced portions 19 (see Figs. l and 3). 20, 20 represent latches composed of a front member 21 and a rear member 22 secured together by screws 23 and between which is pivoted a latch member 24, having a handle 25 and a projecting end 26 adapted to engage with the rack teeth 14. The latch is provided with cleats or keys 27 integral with the latch member 22 which cleats are adapted to be slipped through the large part of slots 18 and then pulled laterally to engage behind the narrow portion of the slots 19 with a wedging it therein so as to become securely joined by a slip jointto the plates 17, and thereby to the window sash 2, but easily removable therefrom. The latch member 21 may be provided with integral handles 2S and 29. To raise the window it is only necessary to grasp the handles 2S and 2.9 and lift the window sash, whereupon the latch member 26 will ride over the rack teeth 11, and when the handles 28 and 29 arereleased the latch member 26 will engage the rack teeth 14 to fasten the window in the position desired. To vlower the window the handles 25 and 2S are grasped and pressed toward one another whereupon the latch member 26 becomes disengaged from the rack teeth, and the window may be lowered to the position desired. It will be understood that while, in the arrangement shown, provision is made for two latches- 20 and two rack members 13, one on each side of the window respectively, nevertheless such Xtures may` be provided for one side of the window only, if desired.

In the modification shown in Fig. 7, a modied form of latch 30 is shown provided with similar cleats 27, 27, for engagement with the slots 18 and 19 but having two pivoted members therein. 31pivoted at 32 is provided with an end portion 33 for engaging the rack teeth 14, while another latch member 341 pivoted at 35, and provided` with a handle 36 carries on its opposite end a weighted portion 37 having a top cam .tace for engaging the rear weighted end of the member 31 so that upon pressing vdown upon the handle 36, the rear One latch member end of member 31 is raised and projection is relatively lowered to disengage it from the rack teeth 13. In both forms of latches the parts are so weighted th'at they return to their normal position shown in the drawings, by gravity, thus avoiding the 'use of springs and other movable parts, which are likely to get out of order.

10, 10 represent another set of rack members provided with rack teeth 11, each hav mg integral therewith cleats or keys 12 for engagement with the slots 11, 12, to secure rack members 40 to the member 5, by slip joints in the same manner that the rack members 13 are secured to the member 5 by the cleats 16. The rack members 13 and a() form front and rear guides -tor the window sash 2, and the rack members 40 form inner guides for the window sash 7 as clearly shown in F ig4 3. Latches or locks 20 are removably secured to the window sash 7 in the same manner that they are secured to the sash 2, and cooperate with the rack members 40 in the same manner that they coperate with the rack members 13. In order to prevent the. rack membersfO from being'pulled or slipped upwardlywhen the window is raised, thumb screws 50 are provided Screw-thread ed therein and havingfend portions 51 engaging. holes 52 in the plate or member 5. These screws 50 are not for-thev purpose of securing` the racks `ll0 to the plate 5, but merely for preventing the. rack members /10 from slipping upwardly relative thereto ali'- ter they have been put into place. The screws 50 are not screw-threaded into the thin metal part 5, but only into the thick portion of rack member 40 so that there is little likelihood of the screw threads there.` on becoming, unduly worn away. The screws 50 are normally hiddenfrom view behind the upper portion oi the window frame. In a similar manner the members 13 may be prevented `from moving ,upwardly when thewindo-w lisraised by means of similar thumb .screws 531eoperating with holes 541 in the members 5.

It-will Vbe notedthat the4 slots 11, 12 are substantially vertical so that there is no danger of `the rack or catch member 13 being forced toward the sash, and binding of the sash iny this manner is substantially prevent'- ed. The restricted portion 19 of the slot 13 beingl extended awa-y from the rack 13 the latch 1s practically locked in place by the rack 13 which prevents the latch from moving laterally and becoming' disengaged.

In order to remove the parts, the thumb screws 53 are lirst unscrewed to disengag'e them from the members 5. The rack members 13 are then pushed upwardly until the cleats 16 comeopposite the large part of the slots 9 whereupon they are easily slipped out and the rack members 13 removed entirely. The window 1 with its sash 2 is thenr easily slipped out of the window frame whereuponl the latches 2O are pushed late ally `so that the cleats come opposite the large portion off window 8 with its sash 7 may be slipped out,

inwardly in a similar manner. By a reversal of operations, all the parts are easily and quickly replaced in a minimum of time and with great ease. It is unnecessary to remove the members 5 or the members 17 because they are normally hidden from view,

and do not require renishing. Members 5 may form part of the window frame or be secured thereto in any similar manner. In {wooden cars they may be screwed to the woodwork. The curtain guide 15 being a part of the rack member 13 is removed simultaneously with it.

While I have described my improvements in great detail and with respect to the preferred form thereof, it will be understood that I do not desire to be limited to such details, since many changes and modifications may be made and the invention embodied in widely dilierent forms without departing from the spirit and scope thereof in its broader aspects.
